Epidural Blood Patch in Patients With Hematologic Malignancies: A Case Series

Area of Science:

• Neurology
• Oncology
• Anesthesiology

Background:

• Post-dural puncture headaches (PDPH) arise from cerebrospinal fluid (CSF) leaks after lumbar punctures (LP).
• Epidural blood patch (EBP) is a standard treatment for refractory PDPH.
• Patients with hematologic malignancies present unique risks for EBP, including potential tumor seeding and bleeding complications due to immunosuppression and thrombocytopenia.

Purpose of the Study:

• To evaluate the safety and efficacy of Epidural Blood Patch (EBP) for treating Post-dural Puncture Headaches (PDPH) in patients with hematologic malignancies.
• To demonstrate that EBP can be a safe treatment option in the appropriate clinical setting for this specific patient group.

Main Methods:

• Retrospective analysis of five patients with hematologic malignancies who developed PDPH after LP.
• All patients had failed conservative treatment and subsequently underwent EBP.
• Imaging (MRI) and clinical outcomes were assessed.

Main Results:

• EBP was successfully performed in all five patients.
• Pre-procedural MRIs showed signs consistent with CSF leak.
• All patients experienced symptom resolution post-EBP, with no long-term complications such as infection or tumor seeding. Thrombocytopenia did not cause procedural failure or bleeding.

Conclusions:

• EBP is an effective treatment for PDPH refractory to conservative therapy in patients with hematologic malignancies.
• Thorough discussion of risks, including infection, bleeding, and potential tumor seeding, is crucial for informed patient consent.
• This study provides valuable insights for proceduralists managing PDPH in this high-risk patient population.
